Through analysis of the components of coking on different parts of desullfur system of single tower and the waste water containing sulfur , we find the cause of coking in the stripping desulur system from single tower is the polymerization reaction of carbohydrate and the separattion of varied solid powders, organic compounds, and all corrosive productions of metal out of waste water in high temperature, therefore,the solving method is how to decrease the oil content ,how to depolymerize form the carbohydrate and how to antisepticize by vapour of waste water.

对单塔脱硫系统中不同部位的垢物及现场催化含硫污水进行了分析测定，结果表明：塔内污垢成分及含量随塔体部位的不同而不尽相同，单塔汽提脱硫系统中垢物的形成，主要是由于污水中所含各类粉尘、有机物、金属腐蚀物等在高温下因石油碳氢化合物的析出及其单体的聚合反应所致。如何降低污水中的含油成分、减少聚合反应的生成、防止污水蒸气对塔体材料的腐蚀，是阻垢、除垢和防垢应解决的关键问题。

按照手性配体的结构类型分类，综述了近年来有机锌试剂对酮、α-酮酯等化合物的不对称加成反应的研究进展，对高效、高选择性的手性配体在该类反应中的应用进行了重点评述。

In view of the polydispersity and unhomogeneous molecular weight of soda lignin in pulping black liquor, the method which firstly classify lignin then react in homogeneous system has been adopted for a long-term to chemically modify the soda lignin, in order to improve the integral performance of lignin technical products effectively. However, there are following drawbacks in this technology: the low ultilization of lignin, and difficult seperation from the reaction system.

鉴于制浆黑液中的碱木素具有多分散性较大、分子不均一的特点，为有效提高技术木素产品的整体性能，长期以来采用先级分木素、后在均相体系中反应的方法，对碱木素进行化学改性，但此法存在木素利用率低产品难从反应相中分出的缺陷。

A particular feature of this crystal is that it reacts to electric currents in predictable ways by untwisting to varying degrees depending on the voltage of the current to which it is exposed. Hence the "liquid" part of the crystal's moniker: Rather than being an oxymoron How can a solid also be a liquid?

水晶的一个特别的特性是它会对电流起可预测信方式的反应藉由根据它暴露潮流的电压分开变化的程度来起反应的，因此水晶标示的液体部分，而不是一个矛盾法又是固体又是液体？

Due to all sorts of physical and chemical properties existed in itself, geological unit may have some adaptability changes, some of which are irreversible, caused by the changes of environment and external conditions, therefore, these unities can accumulate all kinds of information concerning the whole development process.

由于其自身的各种物理和化学性质，地质个体对外界条件和环境的变化存在适应性反应而且有的反应是不可逆的，因此这些个体在整个地质发展过程中不断的累积记录了其所在整体的整个发展过程的各种各样的信息。

The one carbon unit transfer reaction involving in the tetrahydrofolate coenzymes has caused great interest which is very important in the living system and has played an important role in the designing and syntheses compounds (especially the anti-cancer and LCD materials). In our study it was found that benzimidazolium salt has the ability to transfer one or two one-carbon unit and is a kind of new tetrahydrofolate coenzymes model. This research provides new method for biomimetic synthesis.

在非酶催化条件下，不仅实现了与生物体内相类似的一碳单元转移反应，而且可以转移具有不同官能团的取代&一碳单元&，使这种一碳单元转移反应传递的功能化一碳单元更加多样化，这方面强劲的研究工作进展，将为异常活跃的合成化学提供更多常规合成方法难以实现或实现不理想的仿生合成新方法。

That's because he did not know he was eating MSG and other glutamates: like everyone else who complains of allergy or adverse reactions to MSG, Nic has psyched himself into believing that the benign substance makes him feel bad.

原因在于他不知道自己吃了味精或其他谷氨酸：像其他任何一个抱怨对味精过敏或有不良反应的人一样，尼克已经神经过敏了，误以为这种良性物质会让自己感到不舒服。

The epoxidation can be performedwell when the concentration of quaternary ammoniumsaltand sodium tungstate is 0.06 mol/L and 0.03 mol/L, respectively.

结果表明，季铵盐和钨酸钠的浓度分别为0.06，0.03 mol/L时的催化效果最佳；α-和β-蒎烯的转化率随着H2O2与蒎烯的量比增大而增大，当H2O2与α-蒎烯和β-蒎烯的量比分别为2.0和1.8时，其转化率均可达到100%；较高的温度不利于环氧化反应的进行，因此，环氧化反应温度需控制在20℃以下。
